我可以成功SSH到我的服务器。但是，当我deploy:check时，它给了我这个：
Nets-Mac-Pro:mysite emai$ be cap staging deploy:check

The deploy has failed with an error: #<SSHKit::Runner::ExecuteError: Exception while executing on host mysite-staging.nettheory.com: Could not parse PKey: no start line>
Nets-Mac-Pro:mysite emai$
无论我打字什么都行不通，一切都在公开场合。我该如何解决这个问题？
这是我的deploy / staging.rb：
set :rails_env, 'staging'
set :stage, :staging
role :app, %w{mysite-staging.nettheory.com}
role :web, %w{mysite-staging.nettheory.com}
role :db, %w{mysite-staging.nettheory.com}
server 'mysite-staging.nettheory.com', user: 'nt_deployer', roles: %w{web app db}, primary: true
set :use_sudo, false
set :deploy_via, :copy
当我没有设置ssh_options时会发生以上情况。这是我设置时发生的事情：
set :ssh_options, {
user: 'nt_deployer', # overrides user setting above
keys: %w('/Users/emai/Downloads/ilook_ec2_07182014.pem'),
forward_agent: true,
auth_methods: %w(publickey)
# password: 'please use keys'
}
